Independent review of Boeing's Starliner complete, with a total of 80 recommendations:https://www.nasa.gov/feature/nasa-and-b ... t-reviews/
21 of these recommendations pertain to improving testing and ground simulations, including the notable addition of an end-to-end test prior to every Starliner flight;
10 recommendations involve assessing software requirements to ensure the spacecraft is sufficiently tested to meet them;
35 recommendations call for process and operational improvements, including an increased number of participants in reviews;
and 7 recommendations or updates to the spacecraft’s software in order to correct the MET, service module disposal, and communications link anomalies, and to add a new radio frequency filter to narrow the range of communications frequencies Starliner receives and prevent interference
Finally, there were 6 more recommendations for NASA Human Exploration and Operations Mission Directorate to incorporate into future programs:
Require that the systems engineering management plan delivered by each contractor contain specific requirements related to the contractor’s management approach.
Ensure that NASA reviews and approves the contractor’s hazard verification test plans prior to test execution.
Ensure NASA independent validation and verification (IV&V) teams provide insight to contractor IV&V agents.
Implement an approach that ensures alternate standards are reviewed and approved prior to beginning development work.
Develop a best practices document for use by future programs that implement the shared accountability model used in NASA’s Commercial Crew Program.
Evaluate Boeing’s actions developed by the joint independent review team for applicability post-certification.
